CANOPY INSULATION.

Specification of Letters Patent.

Patented June 13, 1916.

Application filed January 25, 1915. Serial No. 4,113.

To all whom it may concern Be it known that I, EDMUND E. BnoH'roLo, acitizen of the United States, residing at the city of Chicago, in thecounty of Cook and State of Illinois, have invented certain new anduseful Improvements in Canopy Insulation, of which the following is aspecification.

This invention relates to improvements in means for affording perfectinsulation to canopies, such as are used for electric light fixtures orcombination fixtures at their juncture with walls or ceilings of roomsor other supports therefor, and it consists in certain peculiarities ofthe construction, novel arrangement and operation of the parts thereof,as will be hereinafter'more fully set forth and specifically claimed.

The principal object of the invention is to provide insulation forcanopies and the like, which shall be of such construction andarrangement of its parts as to reduce the cost of such insulation, bothas it relates to the material, and to the means or manner ofinstallation, or its application to the canopies or parts to beinsulated, as well as, to the packaging of the insulation. 7

Another object is to provide insulation which may be carried in stockalready prepared to be readily applied to the canopy or other article,without the use of rivets or brads, yet in a firm and secure manner, andso as to effectually insulate it from its support.

A further object of the invention is to provide insulation of the abovenamed general character, which can be coiled into compact form so as tobe economically and easily shipped by mail or otherwise.

Further objects and advantages of the in vention will be disclosed inthe following description and explanation.

In the accompanying drawing, serves to illustrate the invention, Figure1 is a view in front elevation of acanopy equipped with insulationembodying the present invention, and showing it mounted on the ceilingof a room or other horizontal support and on or around a supporting pipefor a light; Fig. 2 is a vertical sectional view through a portion oftheinsulation and a part of the canopy showing one form of theinvention; Fig. 3 is a face view of a portion of the canopy andinsulating material showing a modification in the construction thereof;Fig. 4% is a sectional view taken on which line ip-41 of Fig. 3, lookingin the direction indicated by the arrows; Fig. 5 is a view in elevationof a portion of the canopy and lnsulating material showing anothermodification in the construction thereof; Fig. 6 1s a vertical sectionalview taken on line 66 of Fig. 5, looking in the direction indicated bythe arrows; Figs. 7 and 8 are fragmental perspective views partly insection of portions of the canopy and the insulation therefor showingother modifications in the construction of the insulation;

Fig. 9 is a fragmental perspective View of r a portion of the blank outof which another modification is produced, and Fig. 10 is a fragmentalperspective view partly in section of portions of the canopy andinsulating material constructed from the blank shown in Fig. 9.

Like numerals of reference refer to corresponding parts throughout thedifierent views of the drawing.

The canopy or other part to be insulated from a ceiling or other supportis designated by the reference numeral 10, while the ceiling or supportwhich may be horizontal or vertical is indicated by the numeral 11. Asthe invention is more particularly adapted for use as a canopy insulatorit is so shown in the drawing, and will be hereinafter described in suchconnection, but it will be understood that if desired the insulation canbe employed for other articles. As shown in Fig. 1, the canopy 10 ispreferably bellshaped, and is made of metal, but may be of any suitablesize and shape. The smaller end of the canopy is provided with an opening 12, to receive a support-ing pipe 13, which is provided with aninsulating joint 14 of the ordinary or any preferred construction, whichis inclosed by the canopy. In most cases the rim or edge of the canopyadjacent to its support is slightly outwardly flared, as at 15 (see Fig.2 of the drawing), and has at asuitable distance from said flared edgeor rim an inwardly contracted portion 16, from which the material of thecanopy gradually tapers to near its lower or outer extremity, in whichthe opening 12 is formed.

The insulation, which is designated as a whole by the reference numeral17, is preferably made of fiber, but maybe of any other suitableinsulating material of thin,light and flexiblenature, of any suitabledimensions. However, the fiber or insulating material 17 is bypreference produced in long narrow strips, which can be rolled intocompact form,

similar to a ribbon, after its construction has been completed, thusenabling it to be readily packed and shipped by mail or otherwise, insmall or compact packages, or, if desired, carried in stock for sale indesired lengths or quantities. In constructing the insulation, the sheetor strip 17 thereof is by preference folded or bent back upon itself atabout its longitudinal middle or on a longitudinalline about midwaybetween its edges, so that it will present an outer wall 18, and aninner wall 19 in substantial parallelism with one another. The free edgeor portion of the outer wall 18 is bent or folded inwardly to form a ply20, which is extended longitudinally with respect to the strip-ofinsulating material 17, and has its free edge located at a suitabledistance from the juncture of the V outer wall 18, with'the inner wall19, yet by preference against the inner surface of the outer wall, as isclearly shown in Fig. 2 of the drawing. To prevent the strip of materialout of which the insulation 17 is formed being broken by too abruptbending atthe juncture of the walls 18 and 19 thereof, and also toafford a space between said walls for the reception of a portion of thecanopy and of a resting piece therefor, a cord, rod or other suitabledevice 21, is extended in the bend of the strip of insulatingmaterial-between its walls 18 and 19, as is clearly shown in Fig. 2 ofthe drawing.

Located between'the filling piece or cord 21,

and the free edge of the layer 20 of the outer wall of the fiber, is aresting strip 22, for the free or flared edge 15, of the canopy i 10,orother partto be insulated. By reference to Fig. 2, it will beseen'that the edge of the resting strip'22, adjacent to the layer 20, isspaced therefrom so that the flared or out-turned portion 15, of thecanopy 10, may

be interposed between the free edge of the layer 20 and the adjacentedge of the piece 22, as well. as between theouter wall 18 andinner wall 19 of theinsulating material. By this arrangement, it isobvious that the insulating material will not only beheld in position onthe canopy .10, or part tobe insulated, by means of the flexibility orresiliency of the insulating material, but also by reason of theinterlocking engagement of the layer20'with the flaredportion 15 of thecanopy. While it may be preferable to employ the cord, rod 'orfilling21, yet'I do not desire to be limited to its'use, as it may beomitted, in which case the resting strip 22 for the canopy may beextended into and against the juncture of the inner and outer walls ofthe insulating material. In applying the insulating material to thecanopy,

the rim of the latter is inserted between the inner wall 19 and thelayer 20 of the outer wall and forced between the same until the thecanopy or other article to be insulated,

the inner wall 19' of the insulating material is provided witha seriesof inwardly extended tongues or members 23, which are punched out of theinner wall and extended from the latter toward or against the outerwall'18, as will be readily understood by reference to Fig. 4 of thedrawing. These tongues or members 23 are arranged. in a longitudinal rowwith respect to the strip of insulating material 17, and have theiredges opposite the juncture of the walls 18 and 19 alined, and bypreference located at a suitable distance from the layer 20, of theouter wall to permit of the flared portion 15 of the canopy beinginserted in the space between said parts; however it will be understoodthat the layer 20 may sometimes be omitted from the structure shown inFig. 2, as well as from that shown in Figs. 3 and 4 of the drawing, Thetongues 23, which form rests for the free edge of the canopy, have theirends'located transversely with respect to the inner wall of theinsulating material, and are shown as being arranged in diagonally anddivergently inclined pairs,

but is is obvious that if desired they may or may not have the divergentinclination.

In Figs. 5 and 6-isshown another modifioationin the construction of theinsulating 'nal line with respect to the insulating ma terial, incontradistinction to the trans versely disposed ends of the tongues 23of the modified construction shown in Figs. 3 and 4: of the drawing. Thetongues 24 are punched out'of the inner wall19, and afford rests fortheinner edge of the canopy, which is interposed between the layer 20 ofthe outer wall and the inner wall 19, when said layer is employed.

In Fig. 7 is shown a modification, which is of identically the sameconstruction as that shown in Fig. 2, and above described, except thatthe cord or filling 21 is omitted, and that a resting strip 25 for thecanopy, of greater thickness than the resting piece 22, in Fig. 2, isemployed.

In Fig. 8 is shown still another modification in the construction of theinsulating material, which consists in the omission from theconstruction shown in Fig. 7, of the layer 20 of the outer wall 18, andin providing the free edge of the outer wall 18, with an inturnedshoulder or bead 26, which will engage the canopy near its free edge,which free edge is adapted to rest against a resting strip 27,interposed between the outer wall 18 and the inner wall 19, andextending from the juncture of said walls toward the shoulder or head26, but terminating at a distance inwardly therefrom.

In Figs. 9 and 10 of the drawing I have shown a modification in theconstruction of the blank out of which the insulation is made to formthe product shown in Fig. 10. In this modification the insulatingmaterial 17, is provided on one of its surfaces with longitudinallyextended enlargements 28 and 29, the latter being located at the edge ofthe outer wall 19, while the enlargement 28 is located on the inner wallnear the bend or juncture of said walls, but as shown in Fig. 10, theadjacent edges of the enlarged portions 28 and 29 are spaced from oneanother to permit of the reception of the free edge or flared portion 15of the canopy.

In the last named modified construction, as well as in the constructionsshown in Figs. 3 and at and 5 and 6, it is apparent what I claim as newand desire to secure by Letters Patent is 1. Insulation consisting of apiece having an inner and an outer wall united at one of their edges,resting or stopping means for the part to be insulated interposedbetween said walls near their juncture, and an inwardly extended portionon the outer Wall spaced from said resting or stopping means.

2. Insulation consisting of a resilient piece having an inner and anouter resilient wall united at one of their edges, resting or stoppingmeans for the part to be insulated interposed between said walls neartheir juncture, and an inwardly extended portion on the outer wallspaced from said resting or stopping means.

3. Insulation consisting of a piece having an inner and an outer wallunited at one of their edges, one of said walls having near its juncturewith the other wall a series of alined projections extended into thespace between the walls to afford resting or stopping means for the partto be insulated.

l. Insulation consisting of a piece having approximated walls united atone of their edges, one of said walls having near its juncture with theother wall a series of alined projections punched out of the wall andextended into the space between the walls to afford resting or stoppingmeans for the part to be insulated.

5. In a canopy insulation, the combination with a piece of insulatingmaterial having approximated walls united at one of their edges, one ofsaid walls having near its juncture with the other wall on its surfaceadjacent to the other wall resting or stopping means for the part to beinterposed between said walls, and means located on the inner surface ofthe other wall at a distance from the resting or stopping means, toengage the part to be insulated.

6. In an insulation for a canopy having a flared portion, thecombination with a piece of insulating material having approximatedwalls united at one of their edges, of resting or stopping meansintegral with one of said walls near the juncture thereof, and meanslocated on the inner surface of the other wall at a distance from theresting or stopping means whereby space for the reception of the flaredportion of the canopy will be provided.
